A Study on Seismic Analysis of Steel Buildings with Different Bracing Systems

Gokul Akshay Yadav, Jagadeesh Bommisetty, Dr. G. Rajesh Kumar

Abstract


In this paper seismic performance of two types of bracing systems; concentric bracing systems and global bracing systems are compared and studied along with Moment Resisting frame to find out the best configurations. Nonlinear static Push over analysis is performed to obtain capacity curves from which global response of structure is studied. Response spectrum analysis is performed to obtain storey displacements and storey drift ratios for buildings located in Earthquake Zone-V and medium soil condition. Parameters like fundamental period of vibration, stiffness, storey displacements and storey drifts are studied for different configuration of bracings considered and for 20m, 60m& 100m heights of building. Results show every bracing improve seismic performance but relatively GBS enhances significantly followed by K-Braced Frame (KBF) and X-Braced Frame (XBF).
